Final Ligaments notes Flashcards
what is the strongest ligament in the body that runs from the anterior inferior iliac spine to attach distally on the intertrochanteric fossa?
iliofemoral ligament
though the iliofemoral ligament provides the mechanism for you to stand up, if you bend backwards to much strain on this ligament occurs and what muscles are called into action?
the anterior hip and abdominal muscles
when you bend forward what muscles are brought into action to help the iliofemoral ligament?
gluteal muscle
hamstrings
spinal muscles
the iliofemoral is __________ and acts like a ______.
extrinsic and acts like a rope
what ligament reinforces the hip joint capsule anteriorly and inferiorly?
pubofemoral ligament
which ligament attaches from the superior ramus of the pubis to the lower portion of the intertrochanteric line?
pubofemoral ligament
which ligament prevents abduction at the hip joint?
pubofemoral ligament
the pubofemoral ligament is __________ and acts like a _______.
extrinsic and acts like a rope
which ligament reinforces the hip joint posteriorly?
ischiofemoral ligament
what ligament runs from the body of the ischium to the neck and greater trochanter of the femur?
ischiofemoral ligament
what ligament prevents hyperextension and abduction at the hip joint?
ischiofemoral
the ischiofemoral is __________ and acts like a _____.
extrinsic and acts like a rope
what ligament is formed by the acetabular labrum as it bridges the acetabular notch?
transverse acetabular ligament
what ligament converts the acetabular notch into a tunnel through which blood vessels and nerves enter the joint?
transverse acetabular ligament
the transverse acetabular ligament is a ___________ ligament.
intrinsic
what is the weak intrinsic ligament which functions to conduct a blood vessel to the head of the femur?
capitis femoris ligament
what is the anterior ligament of the knee joint that represents the original distal common tendon of insertion of the quadriceps?
ligamentum patella
what is the extrinsic ligament that runs from the base of the patella to the tibial tubercle?
ligamentum patella
important in maintaining alignment of patella relative to articular surface of the femur
what are the extrinsic ligaments that are taut when the joint is fully extended and thus contribute to stability when standing?
collateral ligaments
what extrinsic ligament is located on the lateral side of the knee joint, superficial and separate from the articulate capsule?
lateral (fibular) collateral
what extrinsic ligament proximally attaches to the lateral epicondyle of the femur and distally to the head of the fibula?
lateral (fibular) collateral
the lateral (fibular) collateral functions as a _____ and prevents __________ movement at the joint?
functions as a wall
and
prevents lateral movement
what is the extrinsic ligament located on the medial side of the joint where it blends with the articular capsule and is attached to the medial meniscus?
medial (tibial) collateral
what extrinisic ligament attaches proximally to the medial epicondyle of the femur and distally to the medial side of the tibia (below medial condyle)?
medial (tibial) collateral
the medial (tibial) collateral functions as a _____ and prevents __________ movement at the knee joint.
functions as a wall
and
prevents medial movement
what two extrinsic ligaments are found at the posterior aspect of the knee joint?
oblique and arcuate popliteal
the oblique and arcuate popliteal ligaments function as _______ and prevent ______________ of the joint, while _________ the posterior aspect of the knee.
functions as a wall
prevents hyperextension
stabilzes the posterior knee
what are the two very strong ligaments which cross each other like an X in the center of the knee joint?
cruciate ligaments
anterior
and
posterior
what is the weaker of the cruciate ligaments and runs from the lateral condyle of the femur to the anterior intercondylar area of the tibia?
anterior cruciate
what is the stronger of the cruciate ligaments that runs from the medial condyle of the femur to the posterior intercondylar area of the tibia?
posterior cruciate
what ligament prevents anterior displacement of the tibia under the femur and thus functions like a rope?
anterior cruciate
what ligament prevents posterior movement of the tibia under the femur and functions like a rope
posterior cruciate ligament
